        <!-- Uses the named font object to render axis label or
        tick labels. The object must be created by <ze_font> beforehand.

        <!-- Adds object(s) to the plot.
        
        If the optional vertex attribute is set, the named object must be
        a node that contains objects less than the number of vertex of
        the named vertex object. Objects in the node will be added to
        the plot and positioned according to the vertex of the
        corresponding index.
        
        Otherwuse, if the optional x, y, and z attibutes are set,
        the object will be place at the specified positon;
        and the object will not be scaled by the plot as if it has
        its own coordinate system
        -->
 
    <scale>sx, sy, sz</scale>
        <!-- Scales the object by the factors of sx, sy, sz
        in x-, y-, and z-directions.

        <!-- Rotates the plot about z-axis first then about x-axis.
        If you want to have other rotate effect, put the plot in a node

        Parameters x, y, and z should be -1, 0, or 1.
        If a parameter is 0, the axis object will remain at 0
        of that axis in the global coordinate system; if -1, moves
        the axis object to the left of bottom end; and if 1, moves
        the axis object to the right or top end.
        
        e.g., <xanchor>0, -1, -1</xanchor>
